Exam Focus
- Explain lautering as a brewing analysis topic within Processes.
- Use specific evidence such as raw material form, time, temperature, pH, oxygen, gravity, microbes, vessel, pressure, and sanitation.
- Apply the topic to wort composition, fermentation performance, flavor, stability, clarity, carbonation, and mouthfeel rather than repeating the heading alone.
Core knowledge
- Lautering separates sweet wort from spent grain through mash-out, vorlauf or recirculation, runoff, and sparging.
- Bed compaction, poor crush, high viscosity, huskless grains, and fast runoff can cause stuck or cloudy runoff.
- Excessive sparging, high pH, or hot sparge conditions can extract tannins and create astringency.
Study application
Link runoff behavior and sparging choices to extract, clarity, and tannic mouthfeel.
Key Terms
